Over time, even well-constructed concrete structures can deteriorate and eventually fail. Engineers classify concrete failure into two brittle and ductile failures. Brittle
The list of potential causes of concrete failures is a long one. A few examples include chemical reactions, shrinkage, weathering, and erosion. Many other potential causes exist, and we will
Concrete structures can sometimes fail during service life for various reasons, such as deterioration (spalling due to rusted reinforcements), attack by aggressive environments, lack
Feb 01, Therefore, understanding the time-dependent failure of concrete structures under static fatigue is of critical importance for design of robust civil structures. Previous studies
2.2 Constitutive models of concrete structures Concrete is a complex material with strongly non-linear response even under service load conditions. Therefore, special constitutive models for the finite element analysis of concrete structures have been developed. We shall briefly described some of these models implemented in ATENA
Oct 13, Catastrophic failure of concrete structures in fire, although rare, has been observed in a few instances. For instance, these include the collapse of a department store in Katrantzos in Greece in 1980 and of an apartment block building in
Jan 01, In recent past decades, structural problems related to durability failure of reinforced concrete structures have increased drastically Figure 5.1 presents two columns mechanically damaged due to reinforcements corrosion effects. In this figure, crack growth and spalling phenomena are
Understanding and recognising failure mechanisms in concrete is a fundamental pre-requisite to determining the type of repair, or whether a repair is feasible. This title provides a review of concrete deterioration and damage, as well as looking at the problem of defects in concrete. It also discusses condition assessment and repair
Oct 07, In this paper, the peridynamic theory is used to analyze damage and progressive failure of concrete structures. A nonlocal peridynamic model for concrete columns under uniaxial compression is developed. Numerical example illustrates that cracks in a peridynamic body of concrete form spontaneously. The result of the example clarifies the unique
Failure analysis of concrete structures and adjacent building components at swimming facilities, undertaken for the Copenhagen municipality in all 15 indoor swimming Manned and unmanned visual control and status assessment of sewage plants
Understanding and recognising failure mechanisms in concrete is a fundamental pre-requisite to determining the type of repair, or whether a repair is feasible. This title provides a review of concrete deterioration and damage, as well as looking at the problem of defects in concrete. It also discusses condition assessment and repair
Failures in Concrete Case Studies in Reinforced and Prestressed Concretepresents a selection of the firsthand experience with incidents related to reinforced and prestressed concrete
Oct 15, Concrete anchors are commonly used in both residential and commercial structures to secure structural components to the concrete foundation. Because these anchors are exposed to the foundation, engineers must carefully consider the failure mechanism of the anchors. This failure is most common in cracked concrete, such as that found at the
Jun 05, Structural failures of concrete structures often imply large and unwanted deformations, severe honeycombing and cracking with spalling, relative displacement of supports and ultimate collapse. What type of failures occur in Failure modes in reinforced concrete beams are classified into two major flexural failure and shear
Feb 01, In this paper, the peridynamics theory is used to analyze damage and progressive failure of concrete structures. A non-local peridynamic model for a rectangular concrete plate is developed, and a central pairwise force function is introduced to describe the interior interactions between particles within some definite
